  • Publication number: 20230339539
    Abstract: A method for steering alignment calibration of an articulated machine having front and rear frames pivotally connected by an articulation joint to steer the machine may include displaying a steering alignment calibration screen with a target steering angle between the frames and a calculated steering angle. The calculated steering angle may be determined based on a sensed steering angle and a calibration steering angle. The machine is steered until the displayed calculated steering angle is equal to the target steering angle. If an actual steering angle of the machine is not equal to the target steering angle, further steering is performed until the actual steering angle is equal to the target steering angle. The calibration steering angle may be recalculated and stored for future use when the actual steering angle is equal to the target steering angle but the calculated steering angle is not equal to the target steering angle.

  • Publication number: 20230330595
    Abstract: A carbon capture system includes a hydrogen production module. The hydrogen production module is used to control the amount of hydrogen entering an internal combustion engine to reduce an amount of water vapor generated by the internal combustion engine, thereby increasing the efficiency of the carbon capture device. If too much water vapor is detected in an exhaust of the engine, the amount of hydrogen produced by a hydrogen production module can be increased, thereby reducing the amount of hydrogen entering the engine and reducing the amount of water vapor generated by the engine. A reformer catalyst can be used by the hydrogen production module to remove at least a portion of hydrogen in a fuel stream of the engine.
